    Um, I would strongly recommend against a 4th.

    Low xmax, really high EBP (depending on accuracy of t/s parameters), I still think a different enclosure would work better.

    Doing a 148 out of a trunk is just that, we don't know what your goals are.

    Yes, it still doesn't change that the xmax is relatively low.

    I feel like doing a 4th is just like trying to take a prius off road, you can do it but it'll be difficult.
